Troubles #1 and #3 are not linked to any magnetic equipment or device while #2 seems to be a kind of guess due to the fact that OKK had no real consciourness about the power, density of flux and direction of Earth's magnetic field so close to North Magnetic Pole. Probably there are some heavy iron MASCONS underground fjords like the others well known in the rest of Scandia Peninsula, but those iron masses must have limited local magnetic effects, just like those well localized in Sweden.

Well, if you re-read the first post in this thread, you'll see that the first question was
"What were the major problems with these magnetic torpedoes? ..." - and not
"What were the main problems with the magnetic equipment or device of the torpedos...?"

If you set your magnetic torpedo to pass 1m below an enemy ship but it passes 6 feet deeper than that and doesn't explode 'cause of a problem in the torpedos' balance chamber, you have a problem. ;-)

Both arguments are obviously linked one to the other. Why? this is the correct answer you never did. The reason in the fact tha Earth's magnetic field and the magneti field produced by big iron bottoms of ships are scaled very closely. or the intensity and density of magnetic flux have values not so far 1 from the other. you cannot filter the influence of Earth without altering the scaled values of the ship. Only a ratiometric comparative method (like a scale) could be used.

The course depth is always set by measuring external static pressure with a ratiometric dual-stages baromether. No useful magnetic drive for depth, indeed. No magnetic depth guidance for Z axis but only for planar (X,Y ) flat magnetic guidance. This rule must be applied also to sonic guidance warheads: only an equation to solve in a plane against 6 equations in the space. Btw, I served 20 years ago as torpedo gunner on "Fecia di Cossato" hunter-killer italian submarine: this was exactly my own job. 8)

Thank you very much for your insider view as an expert! :)
